=== GM divisional engines ===
Prior to 1981, the majority of General Motors vehicles were produced with engines designed by their respective divisions. From 1981 onward, GM ended its policy of divisionally-developed engines, instead offering engines under a singular GM brand. As an exception, Cadillac offers division-exclusive engines (the [[Northstar engine series|Northstar]] and [[Cadillac twin-turbo V8|Blackwing]] V8 engine families).

In 1981, GM lost a 1977 lawsuit related to consumers (who purchased 1977 [[Oldsmobile 88#Eighth generation (1977–1985)|Oldsmobile Delta 88s]] equipped with a {{convert|350|CID|L|1|abbr=on}} [[Chevrolet small-block engine (first- and second-generation)#LM1|Chevrolet small-block engine]] instead of the {{convert|350|CID|L|1|abbr=on}} [[Oldsmobile V8 engine#L34|Oldsmobile V8 engine]]).<ref name="Stuart">{{cite news |last=Stuart |first=Reginald |title=G.M.
